OP, march into your county court (guessing you would be in Sandusky or thereabouts) and file for a paternity test (if you didn't sign the AOP at birth), custody, and child support. Ask for the court to force mom to return the child to Ohio or at leats return the child to you. Why do you assume that mom gets to take the child out of state just because? If you wait six months and mom files in Michigan then MIchigan will have jurisidiction. If you file now then Ohio will have jurisdiction.
Moms do pay child support to dads in Ohio. Some couples pay no child support to each other in Ohio. Some dads get full custody or primary custody in Ohio -- even of infants. Especially if mom wants to cut and run.
I've been trying to get a hold of a attorney that was recommended to me, since I have so many questions. Unfortunatly I am having a hard time getting a hold of her. I am from Toledo and need a good lawyer. Could you recommend me any? I will send my e-mail address to you in a PM through this board.
Thanks.
