Should You Pay Waterfall Revenue Group?
Before sending payment, make sure the debt is valid, belongs to you, and is within the statute of limitations. In some cases, paying an old debt can restart the collection timeline, giving the agency more time to pursue you.
Credit repair companies help people handle situations like this and can guide you through the process without making costly mistakes.
Can Waterfall Revenue Group Sue You?
Yes, they have the legal right to sue for unpaid debts. If they take you to court and win, they may be able to garnish your wages or levy your bank account, depending on state laws.
That said, lawsuits are often the last option. Many collectors would rather work out a payment plan or settlement than go through a lengthy legal process.
