Each year, the Ministry of Justice and Security indicates the percentage by which child and partner support may be indexed. As of 1 January 2019, the percentage is 2%. Last year this was 1,5%.
Indexation does not have to be agreed upon by the parties but applies automatically. Only if parties have explicitly excluded indexation in a covenant, indexation will not take place.
Below is a text that you could send to your ex-partner to claim the statutory increase.
As you know, alimony is indexed every year. Last year you paid € ....... a month in child support and € ....... per month in spousal support.
The indexation figure this year is 2%. As of 1 January 2019, I therefore claim the indexation and kindly ask you to pay the new alimony of € ...... for child alimony and € ....... for partner alimony as of that date.
More information on indexation can be found at www.lbio.nl/indexering. Here you can also make your own calculation.
Thank you for your cooperation.
If the indexation has been forgotten for years, it is possible to claim the indexation up to five years ago. Add to the letter that in addition to the last increase, you also claim the indexation up to five years ago. Make a calculation of the difference you would be entitled to.
If your ex-partner is not willing to cooperate in the increase, you do not have to go to a lawyer for this. The bailiff could collect the amounts for you, provided that the maintenance has been established in an order (=judicial decision).
You can make a recalculation of the alimony on the website www.lbio.nl/indexering.
