Shanigan v. Shanigan
386 P.3d 1238
Alaska2017Background
- Elissa and Terrence Shanigan divorced in 2012; Elissa received primary custody of two children and the 2012 child support order required Terrence to pay $1,932.92/month.
- In June 2014 Terrence asked CSSD to review his support; he submitted pay stubs and a 2013 tax return and CSSD extrapolated 2014 income and recalculated support.
- CSSD concluded Terrence’s obligation could be reduced by $315.92/month (to $1,617), a 16.3% decrease that triggered a Rule 90.3(h) presumption of material change.
- Elissa contested CSSD’s calculations, submitting an accountant affidavit showing a smaller reduction ($207.68/month to $1,725.24; a 10.7% change), and argued CSSD erroneously failed to deduct non‑taxable and pre‑tax items and should have required Terrence’s sworn income affidavit (including income from a new consulting business).
- The superior court adopted CSSD’s figure and modified support; Elissa appealed. Terrence did not participate in the appeal.
Issues
| Issue | Plaintiff's Argument (Elissa) | Defendant's Argument (Terrence/CSSD) | Held |
|---|---|---|---|
| Whether CSSD correctly calculated Terrence’s adjusted annual income under Rule 90.3 | CSSD overstated federal and Medicare tax by using gross rather than taxable wages and double‑counting a non‑taxable allowance, producing an incorrect lower adjusted income | CSSD relied on payroll figures and extrapolation; court adopted CSSD worksheet | Court held CSSD miscalculated federal income and Medicare taxes, producing an incorrect adjusted income; CSSD’s calculations were erroneous and should not have been adopted |
| Whether the change in support met Rule 90.3(h)’s 15% material‑change presumption | Using correct deductions the reduction is only ~10.7%, so no presumption of material change exists | CSSD’s (incorrect) calculation showed a 16.3% reduction, triggering the presumption | Court held corrected calculation yields ~10.7% change; no presumption of material change; modification was erroneous |
| Whether the superior court may blindly adopt CSSD calculations | Elissa argued the court must independently evaluate CSSD’s math and the record; petitioner bears burden to prove CSSD wrong | CSSD’s worksheet was presented to court and was relied on below | Court reaffirmed that superior court cannot defer to CSSD; Elissa met her burden to show CSSD’s errors |
| Whether Terrence should have been required to file a sworn Rule 90.3 income affidavit (e.g., about consulting income) | Failure to require affidavit improperly shifted burden to Elissa to disprove other income; affidavit was mandatory under Rule 90.3(e) | Terrence provided pay stubs and some documents but not a sworn income affidavit | Court held it was error not to require Terrence’s income affidavit; affidavit was necessary given unresolved questions (consulting business income) |
