We have a client that we are storing contents for due to a water damage she had at her property. Once the work was complete, she took a long time to pay us - we did not charge her for any extra storage fees while we waited for payment. Once she did pay, she then claimed she couldn't take her contents back due to more work happening at her house. We explained that we can't hold her contents any longer unless she agrees to pay storage fees. She has refused to pay storage fees and also does not want her contents returned to her until whatever work she is having done is complete. Please assist with what kind of legal document we can present to her in regards to notification of storage fees and our rights to sell/dispose of her contents if no payment is received.
