There are always ways to slow the legal system down. Your L can advise you if you want to go that way.
You also may want to discuss w/ L proposing some collateralized loan arrangement w/ W on the house buy-out if you are going to be too pinched. She may not go for it even if it is legally viable. The idea is that you use something of value that will be yours as collateral if you fail to pay the balance of the buyout on the house off. For instance, let's say you hold back $10K and make payments of $5K plus market rate interest in 6 months and a year. Spreads the pain. Just a thought.
I get the feeling frustration that W's choice is leading to setting us back financially. One of our tensions were some financial issues that we both have wanted to handle. Last year, with my increased income, we hoped to make a dent in them. Then she wanted a separation: bye-bye making a dent. Now, we will be duplicating all sorts of things from insurances, utilities, kids rooms in two dwellings. Ugh, now when can we make some progress on the finances. Very frustrating. We just stand up and do the best with what we're handed.
Hang in there.
