18-C M.R.S. § 4-206

The power of a domiciliary foreign personal representative under section 4‑201 or 4‑205 may be exercised only if there is no administration or application for administration pending in this State. An application or petition for local administration of the estate terminates the power of the foreign personal representative to act under section 4‑205 , but the local court may allow the foreign personal representative to exercise limited powers to preserve the estate. A person who, before receiving actual notice of a pending local administration, has changed position in reliance upon the powers of a foreign personal representative may not be prejudiced by reason of the application or petition for, or grant of, local administration. The local personal representative is subject to all duties and obligations that have accrued by virtue of the exercise of the powers by the foreign personal representative and may be substituted for the foreign personal representative in any action or proceedings in this State.
