A lady cleans my house once a week & she speaks no English. Her mother passed away recently & I’d like to express my condolences. Is there a standard Thai expression that people use in this situation?

Thanks

ขอแสดงความเสียใจด้วย

"I wish to express my condolences."

ขอแสดงความเสียใจต่อการจากไปของคุณแม่ด้วยครับ
