Looking for a good fiduciary litigator in NJ

My grandfather passed more than two years ago and I am a beneficiary of the trust he left behind along with my other siblings. He has a building. My first aunt was named the trustee of the trust. This building generates rental income. My aunt who is the trustee also has children who are beneficiaries of this trust. Once the building sells we are to receive a portion of this sale. However, for the past two years she’s been putting the price of the building so high there are no buyers. I am looking for a fiduciary litigator that could help in this type of case in New Jersey. Please recommend. Most lawyers just seem to generate up wills from my Google search so far.
