Can a power of attorney be used to sell my Israeli property without me being present?

Yes — this is one of the most common uses of an Israeli POA. With a properly drafted, notarized, and apostilled POA, your Israeli attorney can sign the sale agreement, receive sale proceeds, pay betterment tax, and register the transfer at the Land Registry entirely on your behalf. Make sure the POA explicitly names all these specific acts, as the Land Registry will scrutinize the document carefully before accepting any transfer registration.
