The August 2022 MA Supreme Judicial Court ruling in Cavanaugh v. Cavanaugh says that judges making orders in contested (1B) cases must look not only at the result of this child support calculation, but also at child support calculations that first calculate alimony, then use the post-alimony-calculation incomes to then calculate child support. A unique Cavanagh alimony, child support, and tax consequences calculator for Massachusetts divorce on this site does the calculations that judges must consider when making orders in contested (1B) divorce cases that could involve child support.
After you have calculated your results and downloaded a court-ready .pdf, you should check your final calculations against the state court’s calculating .pdf at: MA fillable .pdf 2021 child support calculator. You may find the state court form very difficult to fill out unless you you use my website first. If you use my website and download the results as a .pdf, it will give you a guide as to how to fill out the state’s confusing version of the form. The resulting two .pdf’s should be identical.
