so your saying that if we win and he pays us the $10,000 due, but he then thereafter still doesn't pay any dues after the dates we win for, we can't go after him? That doesn't sound correct...
It isn't.
If he's $10,000 in arrears through 2017 and you sue for it, that suit covers that amount. If he defaults for 2018's dues, that's a new lawsuit unless the 2018 dues are already in default.
I used to live in an HOA ages ago, and if you were enough behind in your dues there was some kind of foreclosure process that they would initiate.
True, but there are several problems with that. One is that it can take months or years to go through the process. Two is that the HOA would first have to pay off the mortgage and then give the former owner his exemption then cover its expenses and then get whatever is left.
California's homestead exemption is up to the following limits: $75,000 if single and not disabled; $100,000 if family and no other member has homestead; $175,000 if 65 or older or if physically or mentally disabled; $175,000 if creditors are seeking to force sale of your home and you are either (a) 55 or older, single and earn under $25,000 per year, or (b) 55 or older, married and earn under $35,000 per year. Sale proceeds are exempt for up to 6 months after the sale.
Homestead declaration may be filed to protect the proceeds of a voluntary sale up to 6 months or to protect the exemption amount from a judicial lien.
Foreclosure is likely to be a bad idea when compared to a breach of contract lawsuit for which a judgment will allow wage garnishment and bank account levy.
