Short Answer
In general, yes, it may be possible to sue someone who keeps money that was sent by mistake through a payment app. But whether a lawsuit makes sense depends on several facts, including how the transfer happened, whether the recipient can be identified, how much money is involved, and whether the app itself offers any dispute or reversal process.
In New York, a person who receives money by mistake may sometimes have a legal duty to return it, but that does not mean every case is simple or that a lawsuit will be the best option. Practical issues often matter a lot. For example, if the transfer went to the wrong phone number, username, or account handle, the app’s own policies and the timing of your report may affect what options are available.
A lawsuit may be more realistic when the amount is large enough to justify the cost and effort, or when you have enough information to identify the recipient. If the recipient is a stranger and refuses to return the funds, a claim might be based on general legal theories such as money had and received or unjust enrichment, depending on the facts and the court’s rules. But the exact legal theory, evidence needed, and procedure can vary.
It is also possible that the app provider may be able to help, especially if you contact it quickly. Some payment platforms may be able to flag the transfer, request a reversal if the money is still available, or provide records that may help identify the account. However, app assistance is often limited, and many transfers are treated as completed once sent.
If the money was sent because of fraud, impersonation, hacking, or a scam, the situation may involve more than a simple mistaken transfer. That can change which claims or remedies may be available. Even then, the best next step usually depends on the facts and the amount at issue.
Because New York law and court procedures can differ from other states, and because payment app disputes can turn on technical details, it may be worth speaking with a New York attorney if the amount is significant or if you are unsure how to preserve your rights.

What This Question Usually Means
This question usually means someone used a payment app, entered the wrong recipient, and the transfer was completed before the mistake was caught. The sender wants to know whether the recipient can be forced to return the money and whether court is an option if the recipient refuses.
General Legal Rule
In general, a person who receives money by mistake may have to return it under common-law principles such as unjust enrichment or similar restitution theories. Whether a lawsuit is available and worthwhile depends on the facts, the amount involved, whether the recipient can be identified and served, what proof exists, and whether any app-specific dispute process applies. New York rules and procedures may differ from those in other states.
Key Factors
How the payment was made
Transfers through a payment app are often treated differently from card chargebacks or bank errors. The app’s structure may affect whether the transfer can be reversed or whether recovery depends on a claim against the recipient.
Whether the recipient can be identified
A lawsuit usually requires enough identifying information to name and serve the right person. If the recipient is anonymous or uses limited profile information, recovery may be harder.
Whether the recipient knew it was a mistake
If the recipient realized the transfer was accidental and still kept the money, that may matter to a restitution claim. The details of notice and response can be important.
The amount of money involved
Small amounts may be impractical to recover through court because the time, filing fees, and effort may outweigh the amount at issue. Larger amounts may justify more steps.
App policies and timing
Some payment apps have reporting tools, dispute processes, or limited reversal options. Reporting quickly may improve the chance that the app can freeze or trace the funds.
Whether fraud or scam activity is involved
If the transfer happened because of a scam, impersonation, or account compromise, the legal and practical options may differ from an ordinary mistake.
Available proof
Screenshots, transaction details, messages, and account records may help show what happened and support a claim that the transfer was accidental.
When to Talk to a Lawyer
Consider talking to a New York lawyer if the amount is significant, if the recipient refuses to return the money, if fraud or impersonation is involved, if the payment app is unhelpful, or if you are unsure how to identify the proper defendant. A lawyer may also help assess whether the claim is practical in relation to the amount involved and what evidence should be preserved.
