Hi. My name is*****'m looking at your question now and will post my answer or ask for more information here in a short while.
Recipients of inheritnaces or gifts do not normally pay tax on them. Take a look here for information on when they do.
A legacy to anyone other than your spouse or civil partner is not an IHT exempt one. However, if the deceased estate is not worth more than the IHT threshold of £325,000 (net of any gifts made in the seven years before death) there will be no IHT to pay in any event so your share of the property will pass to your partner tax free.
I hope this helps but let me know if you have any further questions.
