Absolutely — this is a real and distinct request, often called a retention or protection casting. It's designed to guard existing savings, a settlement, an inheritance, or business income from leaks: bad decisions, sudden expenses, or what some clients describe as money that "never seems to stay."
This pairs naturally with a general protection spell, since both are about guarding what's already yours rather than attracting something new.
If you're noticing a consistent pattern of money arriving and then disappearing just as fast, tell me — that pattern itself often points to which kind of work will help most.
