Requirements one by one
Parties, agreement, and approval
Under chapter 180, § 10(a), chapter 180 corporations may combine with each other or with other Massachusetts corporations whose organizing laws permit it. Chapter 180, § 10A(a) permits interstate nonprofit combinations when the other state's law allows them. If a constituent is a public charity, the consolidated or surviving corporation must remain a public charity under either route; the interstate provision requires a survivor governed by chapter 180.
An authorized officer of each party signs the agreement. Chapter 180, § 10(b) requires party and survivor names, the survivor's purposes, terms and conditions, any stock retirement method for a stock party, and a method for fixing effectiveness. The agreement may add lawful provisions, including abandonment terms. Section 10(c) requires each constituent's adoption by two-thirds of members entitled to vote, at a meeting called for that purpose; a stock constituent follows its separate stock vote.
Notice and no-member route
The chapter 180 meeting is called in the manner prescribed by chapter 156B, § 78(c)(1), whose notice procedure gives record holders at least 20 days' notice of the time, place, and purposes, including holders without a vote in its stock-corporation wording.
If the corporation has no members, chapter 180, § 3 substitutes an action or vote of the same percentage of directors for a member action. Applied to § 10(c), that is a two-thirds director vote. Section 10(c) frames the member route in terms of members entitled to vote, so a corporation with members but no merger voting rights must examine those rights under its articles and bylaws.
Filing and effectiveness
Unless abandoned under the agreement, chapter 180, § 10(d)(1) sends articles of merger to the state secretary under chapter 156B, § 78(d). That incorporated section calls for articles reciting adoption, parties, effective date, and applicable charter changes while keeping the agreement separately available. The merger takes effect on filing or a stated later date no more than 30 days after filing under § 78(d). For an interstate merger, chapter 180, § 10A(c) also invokes chapter 156B, § 79(c); a foreign survivor must consent to specified Massachusetts suits and appoint the state secretary for service under § 10A(b)(2).
Chapter 180, §§ 10(d)(2), 10A(d) require the survivor to file a certified copy of the articles or secretary-issued certificate in each Massachusetts registry district where a constituent owned real property, except property of a constituent that itself survives.
What trips people up
Chapter 180, § 10(d)(1) conditions the state secretary's approval and filing where a covered constituent's location changes or the survivor's purposes would require approval by a Commonwealth department or officer for a newly organized chapter 180 corporation. Section 10A(c)(2) carries the same conditions into the interstate route when the survivor is governed by chapter 180.
A corporation unable to comply with the ordinary § 10 process may petition the state secretary under chapter 180, § 7A. The petition must explain the inability and identify known officers and members; the secretary may require further notice and may approve if the statutory findings are met. This is a fact-specific petition, rather than an automatic waiver of the vote.
Common questions
Can a public charity merge into a noncharitable survivor? Chapter 180, §§ 10(a), 10A(a) require the survivor to be a public charity when a constituent is a public charity.
Can the merger be abandoned? Chapter 180, § 10(b) allows the agreement to contain an abandonment provision, and § 10(d)(1) addresses the filing sequence if it is not abandoned.
