Where to file for a divorce in philadelphia.. my husband left me two years ago and I don't know where to find him.

You can file for abandonment.

EDIT:: PA law states:

For all practical purposes, desertion and abandonment are one and the same. . There are two elements that have to be present in order to constitute desertion: the willful desire or the intent to desert and the cutting off the marital relationship. In Pennsylvania, the abandonment has:
Continued for 12 uninterrupted months;

Must be deliberate and final;

Beyond any reasonable expectation of reconciliation.

You still need to get a lawyer.
