Legal Question in Real Estate Law in New York

Re: Can I sign on a USA Affidavit from Israel?

This really depends on what it is you are trying to accomplish with an affidavit. If it is simply to state something about your ownership of real property (rather than to attempt conveyance or mortgaging of such property), your affidavit executed in Israel should generally be sufficient. It may be helpful to do so in front of a U.S. consular official (who is authorized to act in a similar capacity as U.S. notary public) if you plan to use this affidavit in the U.S. as documents notarized by Israeli notaries may or may not be accepted in the U.S. For any transfers, though, you may have to execute a power of attorney in favor of someone who is physically present in the U.S. and make sure in advance it is acceptable to the other parties in the proposed transaction.
