1. Your daughter can take a case under the 1975 Inheritance (Right of Family & Dependents) Act seeking a share in the estate of her father. She needs to act promptly in regard to this application as it must be brought within six months of the date of death of the deceased. In it she will be able to make a claim for any dependency and any care times she spent with him. I would advise her to get herself a solicitor to challenge the will on this basis and get the court to provide for a fairer distribution of assets. I would not advise your daughter to await the production of another will. She can look for one but she should safeguard her position in the meantime.
2. Leaving everything to dogs' home was an abdication of the duties her father owed to her. So she should certainly challenge the will by taking an application to get a share or all of the estate.
