Smith, J.

Neither of tbe plaintiffs having given notice in writing to tbe trustees that be should claim a lien for labor to be performed or materials to be furnished, has acquired any lien on tbe building. G. L., c. 139, s. 15. Tbe lien of tbe several plaintiffs on tbe funds in tbe bands of tbe trustees is determined by tbe priority of their respective attachments.

Tbe value of tbe lumber receipted for by Clough, and fixed in tbe receipt to the officer at §120, should be reckoned as paid by tbe trustees, and be deducted from tbe amount due to Newman, tbe lumber having been used in tbe construction of tbe bouse. Tbe contract is treated by all parties as tbe joint contract of Clough and Young; and that was evidently tbe understanding of tbe parties, although, as between Clough and Young, each was to pay one half of the- contract price to Newman. They are jointly and severally liable to him. It makes no difference that the receipt was signed by Clough alone. It was a liability incurred for tbe defendant Newman, against which they are entitled to secure themselves by withholding that amount from tbe funds in their bands, and which they are equitably entitled to set off against tbe price to be paid to Newman.

They should also be credited with tbe sum of §91.51, paid in *583 settlement of Parker’s claim. Parker had given the statute notice to Clough, and had acquired a valid lien at least upon Clough’s undivided interest in the building, which had priority over the claims of Eastman, Flint, and Hall. Each trustee being liable to Newman for the whole price of the building, the trustees, and each of them, were obliged to pay Parker’s claim to discharge his lien. No question is made as to the validity or amount of his claim.

If the sum of S75 was paid to Newman before service of the writs upon the trustees, it would be a payment to that extent for which the trustees should be credited. If paid after service upon the trustees, and Newman retained the money instead of paying it over to Parker, the payment cannot avail the trustees as against the plaintiffs. But if paid to Parker, whether paid before or after service on the trustees, the payment having been made to discharge a lien upon the property which had priority over the plaintiffs’ lien, the trustees are to be credited with the payment.

The trustees claim that Newman has not completed the building, and therefore is not entitled to receive the full contract price. This claim is in conflict with the reserved case; but if it were not, it would be a question to be determined at the trial term. Whether Batchelder and Moore & Sons have taken executions against the trustees for sums larger than they were entitled to (as claimed by Eastman), is also to be determined at the trial term.

Eastman also raises the question whether, having attached the building as the property of Newman, he may not hold it as Newman’s to the extent that it was not paid for? That question can only be met when the question of ownership is properly before the court. It would seem, however, that if the trustees are charged for the balance due for constructing the building, the question proposed could not arise, the building being fully paid for.

Whether the trustees are chargeable, and if so, for what sum, will be determined at the trial term upon the principles thus laid down.

Case discharged.
