Can I claim for damages to Leather chairs moved to patios by Tenants and carpets damaged by the children?

Tenant said Leather Chairs were moved out to patios because children need more space for toys. Said she did not call me to take chairs out of premises as she did not want to bother me. Told her her action in destroying the chairs is an ultimate disrespect for a Landlord's property. When presented with costs of replacements for damages after deduction of deposit still held by me, she says "I cannot afford to pay you this money so if you want to sue me in court, go ahead." Indicated to her that when I presented the letter with the costs of repair and replacements, I was open-minded and had hoped for a mutual negotiation. She again insisted "I cannot pay you this money, so go ahead sue me in court". I have no alternative but to proceed on this route.
