My stbx lives in Canada. I live in NY.
I sent him uncontested paperwork because we were on the same page and made a custody agreement and was delivered on May 5th through USPS with a signature required. I asked him if he signed and returned the papers and he still has not sent back because he didn't "get time to read them" and it's been more than a month. I thought he had 20 days to dispute. How do get my divorce to go through since he never sent them back?
If you are talking about an uncontested packet, then unfortunately there isn't much you can do except restart the process by having someone serve his personally with the papers. You are not allowed to serve papers and as such time does not start to run until he is served properly.
