Updates to clarify status of ongoing legal disputes involving JPMorgan and WaMu.

NEW YORK (

TheStreet

) --

Lehman Brothers'

case against

Barclays

(BCS) - Get Report

appears to be hitting Barclays' shares, but the dispute involving

Washington Mutual

(WAMUQ.PK) and

JPMorgan Chase

is drawing far less attention.

WaMu and JPMorgan are also fighting it out in the courts, with both companies laying claim to $4 billion worth of deposits, according to an article from June on

WSJ.com

. The article cites an attorney for WaMu who says more than $10 billion is at stake in the case.

The Barclays-Lehman case, which returned to the headlines last week, appears to be weighing on Barclays' shares, which have lagged those of European rivals, including

HSBC

(HBC)

,

Deutsche Bank

(DB) - Get Report

,

UBS

(UBS) - Get Report

and

Credit Suisse

(CS) - Get Report

over the last 10 days, as well as the stocks of many U.S. banks, including

Bank of America

(BAC) - Get Report

,

Wells Fargo

(WFC) - Get Report

and, yes, JPMorgan, which is up roughly 20% since the beginning of June.

In an earlier column, I pointed out that JPMorgan has said it

expects to be sued in relation to the Lehman Brothers case.

Buyers of JPMorgan's stock may be examining the facts of the claims of both WaMu itself and its creditors, as well as the potential ones by Lehman and deciding they won't gain much traction. But there's also a chance that these issues aren't even on their radar, as they have received far less attention than the Lehman-Barclays brouhaha. If that's the case, and JPMorgan suddenly announces a big settlement, it is more likely to be an unpleasant surprise than a pleasant one for shareholders.
