Without seeking special leave, there is a 2 year time frame for either party to apply after the date of separation ... That said, if his name is on the title, it will have to be dealt with at some point & without an agreement, that will involve a court of some jurisdiction or another...who takes who to court ? Worse case I can’t be forced to sell unless he spends that much on a court order ? It’s just his lawyer saying I could end up paying the cost.
We are talking (relatively) small amounts here .... Really can't see any justification to seek legal costs. Just a threat at this point I think it's safe to say
