But not for long... according to this NY Times story, the $1 price discrepancy that currently exists between the price of a marriage license and a domestic partnership registration will soon be going away:
The possibility of a differential, now between fees of $35 and $36, has been a quirk in the city bureaucracy since 1998, when Mayor Rudolph W. Giuliani signed into law a bill on domestic partnerships. But no longer.
Mayor Michael R. Bloomberg’s office has asked the city’s Law Department to work with the City Council and the city clerk’s office on a rule reducing the fee for registering a domestic partnership to $35, according to Matthew Kelly, a spokesman for the mayor’s office.
The change is expected to happen within "several months."
