Child Maintenance and Salary Sacrifice Pension

Hi All,

My ex is a financial advisor very shrewd about his pension.

The last five years or so my Child Maintenance has reduced further (by £100 2 years ago, then an further £100 recently).

I am convinced he is purposefully reducing his relevant earnings through salary sacrifice but the CSA (and now the CMS) don't seem equipped to be able to investigate this or get their heads around. I worked out the earnings they are using are the same as mine. There's no way he's earning the same as I do: this would mean his earnings would have more than halved from 10 years ago, and he is now at a much high-level in his job. So I'm sure he's diverting income through salary sacrifice - as theres no cap on how much you can put into your pension or do salary sacrifice is there anything I can do..? I

Is there anyone in the same situation as me? I am raising our child on a single household income working full time - he has 2 incomes in his household and is supporting his new part-time working partner and their new child: I feel like I am subsidising them and my child is being shortchanged not only finically but also because I have to work long hours to support my son.

Anyone else in a similar situation re the salary sacrifice?

Thanks
