NEW YORK
In New York, a claim must be in writing, state the amount
sought, and contain a recitation of facts upon which the
claim is based. The fiduciary may require the creditor to
present proof by affidavit that (i) the amount sought is
justly due, (ii) any prior payments have been credited,
(iii) the creditor is not in possession of any undisclosed
collateral, and (iv) any indebtedness or other offset of the
creditor to the decedent has been accounted for.
NEW YORK
A New York fiduciary need not search for or send notice
to creditors. The law assumes that creditors exercising
ordinary diligence will send regular bills to the decedent
and the fiduciary will learn of claims through receipt of
the decedents bills. A creditor who learns of the death of a
debtor should send written notice of claim to the fiduciary.
Period for Filing Claims
Creditors must commence a lawsuit on unpaid claims
before the expiration of the applicable statute of
limitations. The period of statutes of limitation varies
depending upon the nature of the creditors claim. Actions
in contract, for example, typically have a longer statute of
limitations than actions for negligence. Death can trigger
special statutes of limitation intended to facilitate the
efficient settlement of estates.
NEW YORK
In New York, there is not a separate statute of limitations
that applies to claims against a decedent and enforced
against the decedents estate. Rather, the customary statute
of limitations to enforce a claim (e.g., six-year statute of
limitations for most contract claims) will continue to apply
to claims after a decedents death.
