I did more research on this. I made some mistakes in my postings earlier. In
https://scholar.google.com/scholar_case?case=6377793034494146442&hl=en&as_sdt=40006 it is a
“pooled checking account” with joint tenancy with right of survivorship, but in my case it is just a joint tenancy with right of survivorship (no pooling). Therefore, the following is not applicable to my case:
In such an account, each tenant "has the right, against the other, only to his or her individual interest in the account" during the lifetime of the joint tenants; funds in the account belong to the parties in proportion to the net contributions by each to the sums on deposit.
Although any tenant can withdraw funds from a JWROS (or JTWROS), there are consequences for that (see at the end of this posting for a case law) if the other tenant or a creditor of other tenant files fraudulent transfer claims.
See
https://www.leagle.com/decision/20022041814so2d122711851 . It is also JWROS (or JTWROS) (no pooling). In that, a joint tenant, who is not facing a lawsuit spent more than her portion of the assets (that is, she spent her husband’s portion also). The court said:
In the instant case, it is undisputed that the Janus account in question was a joint account with right of survivorship and not a tenancy by the entireties. As to such an account, each person has the right, against the other, only to his or her individual interest in the account. Absent other provision, however, the shares in the joint account are presumed to be equal for purposes of alienation….Upon withdrawal by one party, the withdrawing joint tenant is liable to the joint owner for that person's share of the withdrawn funds. …Where a joint tenant withdraws more than his or her share, such a withdrawal is wrongful as between the parties to the account. …It is clear that Maczko's position that she had undivided possession and ownership of the funds as a whole mistakenly confuses a joint tenancy with a tenancy by the entirety…. if property is held as a joint tenancy with right of survivorship, a creditor of one of the joint tenants may attach the joint tenant's portion of the property to recover that joint tenant's individual debt. …Before the bank reached the Janus account, Maczko withdrew the funds, including Iacobelli's share. …While it was certainly permissible for Maczko to withdraw her share, to the extent that the withdrawal also included her husband's share, it cannot be determined that a fraudulent transfer did not occur. …Summary judgment for Maczko was in error as there are issues of fact in this case to the extent that a fraudulent transfer may have occurred and as to Iacobelli's proportionate interest in the joint funds.
Therefore, it seems to me that if my wife withdraw (not spending) more than her share (50%) from our JTWROS account, she will be susceptible to fraudulent transfer claims (although, it seems we both are free to spend the money from that account). Therefore, now she is safe by paying me back $1600, but she must pay half of that $900 also.
I request your further comments.
