Time to find a lawyer that will work pro-bono and 1) Sue the process server and the company he worked for 2) Sue the mother for Fraud 3) appeal the decision and take it to a higher court. Surely a good lawyer could make some money out of this!
This is typical for the state. My sister divorced a while back. Part of the divorce was child support. Her ex paid it to her. The state said he never paid it to her. She said he did and he showed cancelled checks for it. State said that doesn’t prove anything and threw him in jail for three months till he caught it up on work release.
The state of Michigan sucks when it comes to the treatment of men after a divorce. I have so many people I know who were just screwed by the state.
The process server worked for an organization affiliated with the Family Court called "Friend of the Court". . . and it seems to be heavily corrupt. They've been accused of doing similar things to this fake serving of papers, as well as extortion through threats of retribution, and embezzlement of child support payments, etc. No one is willing to touch it. The Attorney General of Michigan won't. They seem to be invulnerable to investigation. . . as they are close to the Family Court prosecutors and judges.
