43 U.S.C. § 443 — Limitation of amount of land holdable under assignment of entry

This section applies to someone who holds land through an "assignment of entry" under federal reclamation law -- meaning the right to a homestead-style land entry was transferred to them by someone else. That person cannot hold more than one "farm unit" this way. A farm unit is the parcel size set for a reclamation project. This limit lasts until the person has made final payment of all the charges owed on all the reclamation land they hold. Only after paying everything off can they legally hold more than one unit. There's one exception: operation and maintenance charges don't count against this limit if they aren't due yet. So a person isn't blocked from holding more land just because future maintenance fees haven't come due.
