Louisiana law has guidelines about who qualifies for in forma pauperis (IFP). The Court has to look into your situation and decide if you qualify. If the court decides you qualify, it will grant the request; otherwise, it will deny the request.
You get a "rebuttable presumption" that you qualify if you give the court "supporting documentation" to show the court one or both of these two things:
Your opponent or the clerk of court can challenge your request to file or proceed in forma pauperis. Such a challenge is called a traversal.
If you have enough extra money in the bank or elsewhere to pay the court costs (or sometimes if you own a home) the court might require you to pay the costs. If you have papers to show you get public assistance (SSI, welfare, food stamps, etc.) or to show your income is less than 125% of the federal poverty level, it is important to attach copies of those papers to the in forma pauperis application. (Blackout any Social Security Numbers on the pages though.)
Financial help from friends or relatives who have no duty to support you does not count toward your income. Hollier v. Broussard, 220 So. 2d 175, 177 (La. App. 3d Cir. 1969); State in Interest of Garrison, 242 So.2d 110, 111 (La. App. 4th Cir. 1970).
