autodisolverse

Used of a group, party, or organization voting to end its own existence, rather than being dissolved by an outside authority — common in reporting on political parties, armed groups, or committees.

• El comité decidió autodisolverse tras cumplir su objetivo. — The committee decided to dissolve itself after fulfilling its goal.
• La organización armada anunció que se autodisolvería. — The armed organization announced it would disband itself.
• Pocos partidos eligen autodisolverse voluntariamente. — Few parties choose to dissolve themselves voluntarily.

Keep the irregular disolver participle in mind — se ha autodisuelto, not *autodisolvido.

Often confused with disolver.
