Short answer. Yes, through an application for support pendente lite. Any party may file a verified application, at the start of the case or any time before judgment, stating the grounds for the claim and both parties' financial conditions, with affidavits or other documents to back it up.
What the law says
At the commencement of the proper action or proceeding, or at any time prior to the judgment or final order, a verified application for support pendente lite may be filed by any party stating the grounds for the claim and the financial conditions of both parties, and accompanied by affidavits, depositions or other authentic documents in support thereof.

Support does not have to wait for the case to end
A case for support can take time to fully resolve, and a child's needs do not pause in the meantime. This rule lets a party apply for support pendente lite — support while the case is pending — so that the child (or other person entitled to support) does not have to wait for a final judgment before receiving anything.
The application can be filed early or later, but must be verified
The rule allows filing at the commencement of the proper action or proceeding, or at any time prior to the judgment or final order — there is no single fixed moment it has to happen. What is required is that the application be verified, meaning the applicant swears to the truth of its contents, not merely alleged informally. This flexibility means a party is not stuck waiting for the perfect moment to raise the need for interim support.
The application has to state grounds and both parties' finances
It is not enough to simply ask for support. The application must state the grounds for the claim and the financial conditions of both parties, and be accompanied by affidavits, depositions or other authentic documents in support thereof. The court needs a real picture of both the need for support and the paying party's capacity to provide it before it can act, since both sides of that picture inform how much support is actually appropriate.
Why building a proper application matters
Because the court decides the application based on what is actually submitted, a bare request without supporting documentation is unlikely to move quickly or succeed. Gathering evidence of both the child's needs and the other party's financial condition — income, assets, and the like — before filing gives the application a real basis for the court to grant support while the underlying case continues, rather than leaving the matter to be decided on unsupported assertions.
