After 20 plus years of working for firms and arguing against opposing counsel seeking that my client pay their fees I can say that the fees charged/billed by law firms and attorneys will be one of the most important yet least known issue of any family law case.
I urge you to read with scrutiny the contract your attorney seeks for you to sign. In the area of Family Law there is never a need to sign a contract that is weighted in favor of the attorney and not you such as the following types of contract - a nonrefundable retainer/initial deposit or a flat fee advance payment contract. There are an overwhelming amount of attorneys use a refundable retainer hourly rate contract. These contracts will identify the amount paid upfront, the charge per hour rate and the frequency/time you are billed at.
