A foster carer may, at any point, give written notice that they wish to resign from the role. After this, their approval is automatically terminated 28 days after receipt of the notice by the fostering service (regulation 28(13)).
The decision maker, alongside the fostering service, does NOT have the power to decline a resignation. Instead, they can only offer advice, informing the carer that their resignation will automatically take effect after 28 days – regardless of whether the notice is then withdrawn.
