The Family Mediation Contract is due to expire on 31 October 2016. You should have received a letter from the LAA (sent on 14 July 2016) offering you an extension to 31 March 2018.
The deadline for returning the offer acceptance form is 23.59 on 4 August 2016. The LAA says that if you do not accept the offer in time, your contract will expire on 31 October 2016 and you will not be entitled to payment for work carried out after that date.
As the summer holidays are upon us, it is possible that the person who would normally deal with the LAA contract is away. It is important that action is taken within the deadline.
