Although this varies by jurisdiction and court, when one party wins and is entitled to attorneys’ fees, that party will make a motion or application to which the lawyers’ bills, expense documents and other evidence of the fees and expenses are attached.
Typically, the losing side will be able to file objections, which might include that the winning lawyers spent excessive time, their billing rates are too high, the case was overstaffed, the winning party wasn’t all that successful, and any number of other grounds. The winning side will usually be able to reply.
After the submissions are complete, the court will decide on whether the requested fees are warranted, sometimes on the papers alone, sometimes after hearing oral argument from the attorneys, and sometimes after having a hearing at which the parties and lawyers present evidence that the fees were necessary and proper.
Generally, the courts try to determine whether the amount of legal time spent was appropriate and whether the billing rates properly reflect the experience, skill and reputation of the lawyers, although there are other factors that can be considered such as the risk the lawyer took in bringing the case and other legal work that he or she may have to turned aside in major cases.
As to the billing rates, some jurisdictions use formulas like the Laffey Matrix, which bases billing rates on the lawyers’ years out of law school and an inflation factor. Other jurisdictions base it more on the rate the lawyer usually collects from free-market paying clients and the court’s experience with attorney billing rates in the legal market.
For commercial and real estate litigation in New York, at least, attorney’s fee requests will usually be based on rates charged to clients paying out-of-pocket, though the judge will almost always give the a lawyer a bit of a “haircut” on the fees requested.
In unusual situations, the court may award the winning side legal fees with a “multiplier” over the regular fees that would have been billed, but this would only occur when the lawyer did extraordinary work where he or she had some personal and/or financial risk in bringing or prosecuting the case.
