For US English: In the title of the court filing, I would use petition. In this case and without more info, I interpret "demanda por cobro" as a petition to enforce collection of an existing order--it would be important not to imply that it is a "petition for establishment of support"--i.e. a filing to request a new support order, but rather a filing to request enforcement of an existing order. Note that spousal support is becoming the preferred terminology over alimony in most states, so if the document concerns that form of support, that would be the preferred term. If it's for children, then child support can be specified, but I think it's ok to use the generic support in the title.

I looked in the EU online term search, and maintenance is apparently the family law term in Europe. I'm from the US and we would use either child support (kids) or alimony (spouse).

The name of the pleading (domanda) would depend on the jurisdiction. It can change from state to state in the US.

I skimmed the initial question and read "EU". Sorry for the confusion. I also speak Italian and live in Italy, so I realize now that I wrote demanda in Italian (domanda).

Alimony is only for a spouse, and is not commonly awarded now in the US.

Generally in US courts, if the demanda is the initial action of a party, it's called a Petition. A Petition initiates proceedings.

So, if the demanda is for children of the marriage, and it is an initial filing, it is called a Petition for Child Support.

Once the court hears the initial Petition, the judge signs an Order for X amount to be paid, which is subsequently enforced and (hopefully) paid.

If one of the parents later wants to change the Child Support Order, then they file a Motion (or a few other possible names, depending on what that court happens to call it).

Perhaps the confusions surrounding translating a demanda is that it can be many things in the US system, and might even change names from jurisdiction to jurisdiction.

So, if you know which state the demanda is for, then that helps to name it.

In domestic/family law practice, usually the divorcing spouses have attorneys representing their interests for the initial Petition, so they Petition the Court to Order Child Support through an attorney.

Then, often, the paying spouse will become unable to continue paying the same amount of child support, so they might file a Motion to Modify Child Support.

When this happens, the filing party might not have the funds to hire an attorney (or might be pretending not to have the funds). Because of this, US states often provide instructions for the filing party to file a Motion to Amend a Child Support Order - without an attorney (pro se).

Here are some examples of pro se motions for the state of New York

They say in law school that procedure is logical, but it isn't until you've learned it.

I hope that helps more than confuses.
