I totally agree Mike. I have not had a pay increase in 5 years, and bonuses of the ''good ol'' days'' of which my wife so much enjoyed are all dried up with just the tax remaining to be paid due to employer''s error.
Just because it''s legally right, doesnt make it so.
I suppose it depends on how the maintenance figures were calculated, mine were based on reasonable need. If the shops, electric/gas prices etc etc go up. I still need to feed, clothe and provide a warm house for the children.
Perhaps an income link for some payers would be more appropriate but this would be impossible to administer and there is no visibility especially if irregular bonuses are received as in my ex''s case.
In the majority of cases, SM is given to the PWC. When parents have no pay rises, they (both) should tighten their belts. Children don''t stop eating or growing just because we don''t get pay rises. In real terms RPI or CPI affects both equally as the PWC has higher expenses with effectively less income - £100 today is worth less than £100 last year and especially if their own wages are frozen as well. Where you have the situation that BOTH parents wages freeze, who should bear the cost of the increased cost of the children?
If no increases were given because the NRP wages were frozen then effectively the children have less income to live on.
Of course, for the people like LMM who pay SM for adults, it is more difficult.
To answer the question the exact terms are important but usually any increase or adjustment applies to the global amount. Of course "adjustment" implies there can be an increase or decrease depending on the index.
