XH has been taking money for personal use such as payment of credit cards and utilities from our joined account through which our rental incomes and expenses are supposed to run.
So, I send him a friendly notice that this is not acceptable and not allowed as per our Marital Settlement Agreement.
In response, XH claims I owe him a total of $2100 for various expenses paid and that he is entitled to the money. I demanded detailed accounting and got a two-liner per email with no details just claims how much I owe him.
So, I killed a couple of beers and some hours today while on vacation and documented every transaction on our joined account as of the beginning of the year which is the start date for all our agreements per MSA, corresponded with our insurance and got all payment details, balances and insurance premiums per car and house and went through all health insurance premiums and each claim since the beginning of the year.
I created a large spreadsheet with individual worksheets, added formulas to calculate each parties' share in debits and credits and voila - even after deducting everything I owe him for HOA fees and insurance premiums paid, he still owes the joined account US$ 600.
Goes to show, it is worth checking everything they say and do when money is involved. $600 pays a nice chunck of my vacation
