Twenty-Fifth Amendment
Presidential Succession & Terms · What happens when a president can’t do the job
Ratified in 1967, in the aftermath of President Kennedy’s assassination exposing real gaps in succession law, the Twenty-Fifth Amendment finally spells out clear procedures for presidential vacancy, disability, and succession that the original Constitution had left surprisingly vague.
Whenever the President transmits to the President pro tempore of the Senate…his written declaration that he is unable to discharge the powers and duties of his office…the Vice President shall…discharge the same as Acting President.
Twenty-Fifth Amendment, Section 3, ratified 1967
The text
Section 1. In case of the removal of the President from office or of his death or resignation, the Vice President shall become President.
Section 2. Whenever there is a vacancy in the office of the Vice President, the President shall nominate a Vice President who shall take office upon confirmation by a majority vote of both Houses of Congress.
Section 3. Whenever the President transmits to the President pro tempore of the Senate and the Speaker of the House of Representatives his written declaration that he is unable to discharge the powers and duties of his office, and until he transmits to them a written declaration to the contrary, such powers and duties shall be discharged by the Vice President as Acting President.
Section 4. Whenever the Vice President and a majority of either the principal officers of the executive departments or of such other body as Congress may by law provide, transmit to the President pro tempore of the Senate and the Speaker of the House of Representatives their written declaration that the President is unable to discharge the powers and duties of his office, the Vice President shall immediately assume the powers and duties of the office as Acting President.
Thereafter, when the President transmits to the President pro tempore of the Senate and the Speaker of the House of Representatives his written declaration that no inability exists, he shall resume the powers and duties of his office unless the Vice President and a majority of either the principal officers of the executive department or of such other body as Congress may by law provide, transmit within four days to the President pro tempore of the Senate and the Speaker of the House of Representatives their written declaration that the President is unable to discharge the powers and duties of his office. Thereupon Congress shall decide the issue, assembling within forty-eight hours for that purpose if not in session. If the Congress, within twenty-one days after receipt of the latter written declaration, or, if Congress is not in session, within twenty-one days after Congress is required to assemble, determines by two-thirds vote of both Houses that the President is unable to discharge the powers and duties of his office, the Vice President shall continue to discharge the same as Acting President; otherwise, the President shall resume the powers and duties of his office.

How the Disability Process Actually Works
The president declares their own inability
A president can voluntarily transfer power by written declaration — used, for example, during brief medical procedures requiring anesthesia. Power transfers immediately and returns the same way, by the president’s own written declaration of recovery.
The Vice President and Cabinet can act without the president’s consent
If the President can’t or won’t declare inability, the Vice President plus a majority of the Cabinet can jointly declare it instead — the most contested and least-used provision, since it involves removing power from a sitting president who hasn’t agreed to it, with the president able to contest the determination and Congress as the final arbiter.
Section 4 has never actually been invoked
A common misconception is that this amendment’s disability provisions are a routine, frequently used mechanism. Section 3’s voluntary transfer has been used a small number of times for planned medical procedures. Section 4’s involuntary removal process — the one most people picture when discussing presidential incapacity — has never once been formally invoked in the amendment’s history, despite being discussed in several real political moments.
