- Child Maintenance Service – Policy, Law and Decision Making Guidance

The Child Maintenance Service (CMS) is administered by a department within the Department of Work and Pensions (DWP) called the “Child Maintenance Group” (CMG).
We have been sent copies of a set of documents called “Policy, Law and Decision Making Guidance” (PLDMG). If you saw our recent post on Child Maintenance Policies then you will have started to understand the processes that caseworkers go through (or should go through) when dealing with CMS cases.
The PLDMG contains the detail around those processes, what the CMS is and is not allowed to do as well as the legal guidance available to caseworkers that they “should” be following.
If a similar mistake or omission has been made in your case you may have legal redress to the CMS. In any event, we hope that by giving our readers the access to these files you will be able to ensure that your case is administered in the proper way, and, if not, that you will be able to complain citing the correct policies.
Here is the full list of documents in the PLDMG:

As you can appreciate, there is a lot of information in the PLDMG and we will be going through it and highlighting various sections in individual posts in the future. In the meantime, we would like your help in identifying things that the CMS has not done (but should have done) with respect to your cases.

In a Family Law system designed for combative parents there is no real allowance for the views of children and any understanding of how Family Law ultimately impacts on children most of all.
We speak for the children in Family Law so that, finally, the children have a voice.
