# Changes to make
# Validator self-unbonding (which exceed minimum self delegation) could be required to start instantly
Cases that trigger unbonding process
- Validator undelegate can unbond more tokens than his minimum_self_delegation and it will automatically turn the validator into unbonding In this case, unbonding should start instantly.
- Validator miss blocks and get slashed
- Validator get slashed for double sign
Note: When a validator begins the unbonding process, it could be required to turn the validator into unbonding state instantly. This is different than a specific delegator beginning to unbond. A validator beginning to unbond means that it's not in the set any more. A delegator unbonding from a validator removes their delegation from the validator.
