The servicer must pay counsel a reasonable fee for services rendered if additional legal services are required to protect Fannie Mae's interest and the legal services
are not within the scope of services contemplated by the maximum allowable foreclosure fee; and
are required due to a breach or alleged breach of selling warranties or representations or origination or selling activities or to the lender’s failure or alleged failure to satisfy its duties and responsibilities as a servicer. In these circumstances, Fannie Mae will not reimburse the servicer for the fees.
