I have been granted a global maintenance order until youngest child reaches 18. Basically I will get £x amount each month less any CSA payments. This provides protection for the childrens and my income needs despite what happens to CSA payments. It will only be granted if your ex''s outgoings are considered reasonable and it can be shown there is ability to pay.
Global maintenance is usually paid when the payer is on a high income and their is a substantial amount of SM. The court is directed only to limit SM to a term that can be identified when the recipient can become self-sufficient. If no such term can be identified a joint lives order is likely.
When there is a joint lives order or no bar to extending the term the advantage of global maintenance from the payers POV is that when CM, CB and tax credits end SM will automatically increase reducing the chances of a variation being sought. Apart from the legal costs, which aren''t insignificant, if a variation is applied for the court will consider both parties circumstances again and there is always a risk of being ordered to pay more.
