I wonder how long this is going to take.
Guy and Gal have a one night stand and never see each other again.
Gal ends up pregnant.
25 years later, guy is located and he has to pay back all those years of “child support”, plus interest.
Heck, maybe its happened already.
Most states limit how far back retroactive child support orders can look, unless there are special circumstances. Texas is four years, CA is three.
The longer a custodial parent waits, the less likely they are to prevail and the numbers will be based on the non custodial parent’s income for the years in question and not the present day, unless you can prove they were hiding income and assets.
A suit based on a 25 year wait wouldn’t make it into the courtroom, unless there were some really interesting circumstances generally only found in soap operas.
