Aрpellant challenges the trial court’s enforcement of the parties’ separation agreement as part of its Judgment of Absolute Divorce. The trial court found that the agreement, which was contained in a letter signed by both parties, was complete and unambiguous on its face, and that the parties had demonstrated an intention to be bound by it. Consequently, the trial court found that the agreement is an enforceable contract, and required appellant to provide appellee with an accounting of the child support that was in arrears under the terms of the separation agreement, pay the outstanding amount within thirty days, and continue to pay child support in the amount provided for in the separation agreement. Finding no error in the trial court’s judgment, we affirm.
I.
The parties were married in Grand Rapids, Michigan on December 29, 1977. They adopted a daughter, born on September 19, 1995, who began residing with them on September 21, 1995. In 1998, appellant decided he wanted to separate from his wife. During their separation, the parties worked together to sell their marital home, divide the proceeds, pay their various debts, and distribute them personal property.
The рarties also devoted considerable time and attention to resolving other issues of their divorce. At appellant’s recommendation, they met with a lawyer who specialized in divorce mediation. They also met on their own on several occasions and had extensive discussions about their respective settlement concerns via e-mail.
In an effort to save time and attorney’s fees, the parties negotiated an agreement on the terms of their divorce, which the appellee reduced to writing in the form of a letter addressed to her attorney, whom the parties agreed would then prepare a formal agreement incorporating the terms they agreed upon for review by appellant’s lawyer. The letter dealt with a broad range of outstanding issues, including financial terms, child support, and the legal and physical custody of their daughter. *633 On May 12, 2001, both parties read over the letter drafted by appellee and signed it (hereinafter referred to as the “Letter”).
Soon after, counsel for appellee prepared a Marital Settlement Agreement (hereinafter referred to as the “Draft Agreement”) incorporating the terms set оut in the Letter, and sent it to appellant on May 23, 2001. 1 Although appellant did not execute the Draft Agreement, the parties abided by the terms set out in the Letter from May 2001, when the Letter was signed, until November 2002, when appellant unilaterally reduced his child support payment from the $5000 per month provided for in the Letter, to $2000 per month.
Appellant filed a Complaint for Absolute Divorce, Custody and Related Relief with the Superior Court of the District of Columbia on February 11, 2002. Upon dismissal of his complaint by stipulation, he filed an Amended Complaint on December 27, 2002. With her answer, appellee simultaneously filed а Counter-Complaint for Absolute Divorce and Related Relief contending that in the Letter the parties had resolved all issues remaining from the marriage. At trial, appellant testified that his main point of contention was the amount of child support set out in the Letter ($5000 per month), and that he challenged the enforceability of the Letter as an agreement primarily in order to have the court reach an independent judgment as to the appropriate amount of child support, which he proposed should be $2000 per month — the amount to which he had reduced his monthly support payment in November 2002. The trial court determined, however, that the Letter is an enforceable contract, and in the order granting appellant’s complaint for divorce, ordered past and ongoing child support to be paid in the amount specified in the Letter.
II.
The law in this jurisdiction encourages the use of separation agreements to settle the financial affairs of spouses who intend to divorce.
See Bracey v. Bracey,
A separation agreement is a contract, subject to the same law governing other contracts.
See Owen v. Owen,
A. Agreement to all material terms
In order for a contract to be enforceable, it “must be sufficiently definite as to its material terms (which include,
e.g.,
subject matter, ... payment terms, quantity, and duration) that the promises and performance to be rendered by each party are reasonably certain.”
Affordable Elegance Travel, Inc. v. Worldspan, L.P.,
We agree with the trial court that the Letter was both complete and definite with regard to the terms of the parties’ dissolution of their marriage. According to the Letter:
Brian [appellant] and I [appellee] have agreed upon the basic terms of the divorce settlement, as we understand them in lay terms. The key items are outlined below. We would like your help to create a document that expresses these intentions as well as any other items that need to be included in such a document. It is our intent to then forward the document to Brian’s lawyer for review.
The language of the Letter therefore shows that the parties understood themselves to have “agreed upon the basic terms of the divorce settlement.” This understanding is borne out by the terms covered in the Letter, which memorialized the parties’ agreement on thirteen separately listed items: joint legal custody of their daughter, with appellee as the custodial parent; vacation and visitation rights and costs; division of proceeds from the
*635
sale of their home; ownership of appellant’s life insurance policy; transfer of funds from appellant’s 401K account; health insurance coverage for their daughter; sharing of costs of their daughter’s education and wedding; the absence of any restrictions on the parties’ future place of residence;
2
the absence of marital debt; and child support at the rate of $5000 per month.
3
The child support — as to which appellant has expressed primary concern — was clearly articulated in its own clause, and was specific as to amount, manner of payment, and duration.
4
Thus, the parties could be clear about their obligations and expectations, and, in the event of a challenge, a trial court would be able to determine whether there had been a breach of the child support agreement and to fashion an appropriate remedy.
See Affordable Elegance Travel,
In support of his argument that the Letter does not evidence a meeting of minds on all material terms, appellant asserts that it lacked a regular visitation schedule for him to see his daughter, or agreement regarding the division of their рersonal property (“furniture and whatnot”). But the Letter did address “vacation and visitation” with his daughter,
5
and contained a provision specifying the division of the proceeds from the sale of their house. Although the Letter did not provide for the division of personal property, testimony at trial demonstrated that the parties had divided the household furniture and other personal property
prior
to the signing of the Letter. Viewed in the context of the parties’ previous dealings, the Letter therefore disposed of all remaining marital property, real and personal, and arranged for the child’s сustody, visitation, and support, including monthly child support, ongoing health insurance, college and wedding costs. Since there was no material issue left undisposed and the terms were clear, the Letter was sufficiently complete to be enforceable.
See, e.g., Spires v. Spires,
We disagree with appellant’s contention that a comparison of the terms of the Letter and the Draft Agreement prepared by appellee’s lawyer shows that the Letter was incomplete. The minor differences in language between the Letter and the Draft Agreement do not go to the substance of the agreement, and merely further specify foreseeable details. 6 Appellant does not explain how the expense items listed in the Draft Agreement are materially distinct from the Letter’s more general terms, “undergraduate collеge education” and “wedding,” nor does he contend that those more general terms are so vague as to preclude the parties from reasonably knowing how to perform their obligations under the Letter.
The Draft Agreement also added provisions for attorney fee shifting in the event of breach or default by either party, and for the payment of their daughter’s un-reimbursed medical expenses. Terms providing for how parties will allocate attorney’s fees incurred in seeking redress for a breach of contract are not necessary for the parties to understand how they are expected to perform the contract itself.
See Hackney v. Morelite Constr., D.C. Corp.,
The record supports the trial court’s finding that the Letter was “intended to be the complete and final agreement between the parties,” and that it is “clear on its face.”
B. Intent to be bound
For an enforceable contract to exist, the court must not only determine that there was an agreement to all material terms, but also that the parties intended to
*637
be bound.
See Jack Baker, Inc.,
Both appellant and appellee signed the Letter, the clearest evidence of mutual assent to the terms of the document.
See Davis v. Winfield,
Appellant argues that the trial court overlooked that the Letter also demonstrated his intention to have his attorney review the final document,
11
and that such review therefore constituted a condition precedent to enforcement of the settlement agreement. Whatever ambiguities may be inherent in the provision for the lawyer’s “review,” the Letter unambiguously states that the parties “have agreed upon the basic terms of the divorce settlement,” expressing a meeting of the minds with respect to the terms of the agreement.
See Owen,
I would be agreeable to having your attorney’s assistant draw up the appropriate legal papers, and not have to pay Cam [a mediator] any more money (and make another trip to Rockville). I would then simply have my lawyer review the paperwork and tell him that the papers reflect whаt you and I have decided to do.
In taking steps to immediately abide by the terms of the Letter he signed, after having stated that he only wanted a lawyer to ensure that “the papers reflect what you and I have decided to do,” appellant demonstrated that the review he contemplated *638 by his attorney was merely for the purpose of ensuring that the language of the final document would embody the terms to which he agreed in the Letter, and not to reconsider those terms. Thus, the record supports the trial court’s finding that the parties intended to be bound by the Letter. Based on this finding and the trial court’s finding that the Letter covered the material terms of the parties’ divorce settlement, we agree with the trial court’s conclusion that the Letter is an enforceable agreement.
III.
During trial and on appeal appellant has expressed concern that the Letter does not address what would happen to his child support obligation in the event he lost his job, or had other financial constraints. Although provision for future contingencies could well have been part of the parties’ agreement,
12
it is not a necessary component for enforceability becausе, to be complete, a contract need only be sufficiently definite so that the parties can be reasonably certain as to how they are to perform.
See Affordable Elegance Travel,
The standard for granting a modification to child support specified in a settlement аgreement depends on whether the agreement was merged into the court’s judgment, or incorporated by reference. The trial court has limited authority to alter a child support provision in a separation agreement that is incorporated, but not merged, into an order of divorce, due to the “presumption that ‘a child support agreement negotiated between two parents is adequate to meet the child’s foreseeable needs, and that at the time of the agreement the best interests of the child were a paramount consideration.’ ”
Clark v. Clark,
Thus while a court may find that a child support agreement does not provide a sufficient amount of money to meet a party’s legal obligation to support and may order a larger sum to be paid ... it may not modify such an agreement by reducing the agreed upon amount to the minimum the law would impose in the absence of an agreement, or to any sum different from that provided for in the agreement.
Lanahan,
Where a settlement agreement is merged into the trial court’s order, on the other hand, the binding force of the amount of child support is not based on the contraсtual obligation arising from an agreement between the parties, but on the authority of the court’s order.
See Hamel v. Hamel,
A settlement agreement is merged, and not merely incorporated into a court order, where “the agreement was adopted by the court as its own determination of the proper disposition of the rights and property between the parties.”
Hamel,
Though other jurisdictions have enunciated criteria for determining whether a settlement agreement has been merged or incorporated into an order of divorce,
see, e.g., Johnston v. Johnston,
The record in this case shows a serious, sustained effort by mature adults seeking to come to a reasonable agreement about their рroperty and, most important, their continuing responsibility to and relationship with their child. Appellant may now regret that he entered into an agreement without first seeking the advice of counsel, or he may think, after the passage of time, that he should not have agreed to the terms contained in the Letter. These doubts do not negate that the Letter is complete as to the essential terms of the parties’ divorce, and that appellant’s course of conduct for over a year — from signing the Letter, to abiding by its terms, to stating in his e-mail communications his desire that any formalized agreement incorporate the terms in the Letter — demonstrates his intent to be bound by the conditions set forth in that agreement.
For the foregoing reasons the trial court’s Judgment of Absolute Divorce enforcing the terms of the separation agreement is
Affirmed.
Notes
. It appears that appellant was not represented by counsel at the time. In her letter to appellant enclosing the Draft Agreement, ap-pellee’s counsel advised appellant that she did not represent him and that he had a right to be represented by an attorney and should consult one if he had any questions or concerns аbout the Draft Agreement she had prepared.
. E-mail communications between the parties also demonstrate that both parties understood their agreement included no restrictions on residence.
. While the Letter includes a significant amount of child support, it does not provide for alimony. Alimony, however, is not a necessary element of a divorce settlement, and neither party contends entitlement to alimony.
. The Letter reads as follows on the subject of child support:
Brian agrees to pay child support to Joan until [their daughter] reaches the age of 18. Brian will depоsit $5,000.00 per month (beginning September 1, 2001) into Joan’s checking account. This child support will be non-taxable to Joan or Brian. Joan would also like a clause that states that amount will be adjusted annually to reflect the then current Consumer Price Index.
.The Letter provides in this respect:
Vacation and visitation to be arranged as follows:
-Brian may have [daughter] for three weeks during her summer vacation.
-Joan and Brian shall each have [daughter] for major holidays (Christmas, New Years, Thanksgiving, Easter) in alternating years. -All other details and considerations to be handled on a mutually agreed basis.
With respect to visitation, the Letter states: Joan shall provide accommodations and transportation for Brian while he is visiting [their daughter] and two hundred and fifty dollars for each of his monthly trips to visit [her].
. For example, the Letter provides that the parties "will each bear half the cost of [their daughter's] undergraduate college education and her wedding expenses.” With respect to college education, the Draft Agreement states that "[t]he parties shall each be responsible for fifty percent (50%) of the costs of SATs, SAT tutoring, pre-application college visits, reasonable travel to and from school, tuition, room and board, books, registration and ancillary fees, and reаsonable application fees incident to providing [their daughter] with a four year undergraduate college education.” And with respect to a future wedding, "[t]he parties shall each be responsible for fifty percent (50%) of the costs associated with [their daughter’s] wedding and reception.”
. With respect to health insurance, the Letter provides:
Brian will provide customary health coverage; including major medical, health, dental and vision coverage for [his daughter]. Joan will pay the annual deductible up to $500. Brian will modify his policy to reflect an annual deductible ... of $500 rather than the current $1000.
.In his brief, appellant makes the related argument that the differences between the Letter and Draft Agreement indicate that the Letter was merely an "agreement to agree.” Appellant seems to have abandoned this theory at oral argument. As noted in the text, none of the additional elements introduced in the Draft Agreement was significantly different or necessaiy for the performance of the terms memorialized in the Letter. Thus, they were not material, and did not undermine the binding nature of the agreement memorialized in the Letter.
Cf. D.C. Area Cmty. Council, Inc. v. Jackson,
. Appellant had begun paying child support in the agreed-upon amount on July 31, 2001, though the Letter stipulated that payment would begin on September 1, 2001.
. The trial court noted that appellant had not transferred funds to appellee from his 40IK account as provided in the Letter. She also noted, however, that the trial court’s order would be necessary to effect the transfer.
.The Letter states that "[i]t is our intent to then forward the document to Brian's lawyer for review.”
. We note, for example, that the Letter states that "Joan would also like a clause that states that amount [of child support] will be adjusted annually to reflect the then current Consumer Price Index.” This statement reflects that although some contingencies were considered, the parties did not incorporate them in their agreement.
. Contrary to appellee’s representations on appeal, the Draft Agreement prepared by ap-pellee's counsel provided that it would not be merged into the court’s order, and the appel-lee’s counter-complaint similarly requested that the Letter be incorporated, but not merged, into the judgment of divorce.
