Funny you should ask. Here is how I did it:
Borrowed from friend
Sold the car
Remortgaged the house
Added a second mortgage on the house (with the decline in real estate values, the loans on the houses are higher than its market value)
Paid the retainer through credit cards (lawyers now accept credit card)
Borrowed from other friend
Wrote cheques on the credit card, the other credit card and the other credit card until ran out
Used all my tax refund
Used my overdraft protection
Now, I am all out. So, I am thinking to sell one of my kidneys or part of my liver to pay my lawyer. My ex on the other hand enjoys a hefty spousal support, a vacation like life style, free housing, under the table wages, and free lethal aid from the govt (oops...I meant legal aid)
Sorry no mercy in the world of family courts on those who work hard. You just have to come up with cash to pay the lawyer like everyone else in this system.
