Collecting from deadbeat customers
Have the lawyer write them a short letter of warning, giving them a grace period to pay the bill, with an explanation of the whirlwind they'll suffer if they don't pay.......Lawyers will generally not charge too much for this service (if you know them, that is).........After that, they can file for a judgment against the customer that will go on their credit report for the due balance plus legal expenses. Most customers will try to clear up the debt instead of facing the consequences. They won't be able to buy a house or car, or perhaps even get a credit card unless they clear up the debt.
In many states, the lawyer can file for a "mechanics lien" against the balance........it's placed on their property so that when it is sold, you get paid first. Noit very practical though if someone holds their property long term.
I've found that a letter from a law office is usually effective.
