Here is a case from the Bronx in which a matrimonial client unsuccessfully sues her attorney.  Case is dismissed on the statute of limitations.  This was a pro-se plaintiff  v. pro-se defendant case.

"From June 12, 2000 to September 7, 2000, Plaintiff KINBERG retained Defendant GARR to represent her in her matrimonial Action, (which had been pending since 1992). This is evidenced by the parties’ retainer agreement which provides that the legal services that GARR would be providing would be in connection with the then-pending Action, entitled Kinberg v. Kinberg, Index No.: 72304/1992, in New York County Supreme Court. (See Plaintiff’s Exhibit "C"). The matter was scheduled for trial, on the equitable distribution of the marital assets, before the Hon. Justice Jacqueline Silbermann, on September 7, 2000, when the parties entered into a settlement Agreement, and KINBERG took the stand where she was allocuted on the Agreement. KINBERG testified that she understood the Agreement, wanted to accept it, and was satisfied with the services of her Counsel.

The rest of the decision documents the 6 year trail of litigation which ensued.  Plaintiff was successfully sued by the attorney, then she lost an action against her former husband, then lost an action against the attorney, and now, once again, loses.

If the attorney had not sued for his fees, would there have been 5 more years of litigation?
