The idea is to move towards parents making their own private arrangements and in the future the CSA will be charging both parents with care and non resident parents. If parents have a written private agreement it may be enforced through the small claims court like any other debt.
Under the current CSA rules to qualify for a reduction to the amount of child support the NRP pays, a the debt must have been incurred for the benefit of the NRP and the PWC or any qualifying child and any other child in the household
Debts which could qualify for a variation are those which, for example, were incurred to purchase furniture or computer equipment, a family holiday or home decoration or alterations.
If the NRP continues to enjoy the benefit of the item or service which gave rise to the debt, the application will be excluded.
Also excluded are credit card debts, business debts, debts relating to the costs of separation, divorce, or dissolution of a civil partnership, fines and loans obtained other than from an employer, bank, building society or other registered lending institution. Therefore your husband''s car and loans won''t qualify for a variation.
Your husband is liable to pay CM, but if you enjoy the sole use of the former
matrimonial home it could be said you should pay your share and your ex''s share in lieu of rent for occupying his share of the property. It is usual for separated spouses to pay their own household bills. So you may not be any better off claiming child support. If you are left struggling you may be able to claim maintenance but generally someone on average or below average income won''t be deemed to have the ability to pay maintenance.
The expense of solicitor is relative. If you pay £1.5k and you are better off by £200 a month for the next 10 years it is money well spent.
