House in divorce??

My husband and I are getting a divorce without a dispute https://onlinedivorcer.com/blog/toxic-marriage-signs. We have everything divided and agreed upon...except the house. I moved out 3 months ago (because he didn't want to). He agreed to leave me the house after the divorce. The house is in my name only, as I bought it 7 months before we were married (we lived in it for 15 years). He didn't want to buy and refused to pay for it for years. The problem is that he allows me to take the house, but does not give me a date by which I must return. He wants a minimum of 6 months to find something. That means I will either have to move back in when the lease is up, or try to switch to a monthly lease until he finds something. The main problem is that I don't think we can put an unknown date on the divorce papers. I think if there is no date, he will procrastinate in finding a place to live (he's not very motivated). If I put a date on the papers in 6 months, I don't know if he will sign the papers. I don't want to settle for an unknown date when I get back into the house after our divorce.
