Downton Abbey  devotees and law students alike must have heaved a collective sigh of relief with the return to our screens of that compulsive lesson in legal history, cunningly disguised as a period costume drama.
Those who have not been drawn into the mystery and intrigue of the occupants of Downton Abbey, who seem to have suffered more communal misfortune than one would reasonably expect of an extended family (but no doubt a requirement for the television ratings), can stop reading now.
All others, take note for our first tutorial, of the references to the outdated (even then) but shortly to be amended laws on intestacy  (Matthew failed to make a will) resulting in Lady Mary’s diminished share in the estate and looming spectre of heavy death duties.
While death at an early age is always tragic and as was observed of Matthew, he anticipated being around for many years thence, what happens on intestacy  generally seems to come as something of a shock.
The rules, which determine the distribution on a person’s death of any of his or her property not governed by a valid will, are largely contained in the Administration of Estates Act 1925 (spookily coinciding roughly with the current Downton period - will Lord Grantham vote on it in the House of Lords?) and the Intestates’ Estates Act 1952.
By and large these have not kept pace with the requirements or expectations of modern family life. Back in 2009 the Law Commission published a consultation paper on various aspects of the rules, some of which have been included in the Inheritance and Trustees’ Powers Bill 2013 which is working its way through the House of Lords as I write.
Under the current provisions, however, in the absence of a valid will by Matthew, because his estate is likely to have been valued at more than £250,000 and he was survived by a wife and child, Lady Mary's entitlement today would still be limited. She could claim for herself a statutory legacy of £250,000 and all of Matthew's personal chattels.
The balance of Matthew's estate would then be divided in two with Lady Mary receiving a life interest (ie income only) in one half of the estate. The gorgeous George would be entitled to the other half of the estate on statutory trusts and the half of the estate in which his mother has a life interest, on her death.
This was probably not the result she and Matthew (or indeed Lord Grantham) were hoping to achieve by virtue of their collective and cumulative efforts in the previous three series. Do note, however, that in certain circumstances, the provisions of intestacy can be varied in the same way as one can vary a will.
However, in my experience what is sometimes more surprising for clients is not necessarily the effects of intestacy but the fact that despite having gone to the trouble of officially anticipating one’s demise and providing for it (as far as one's property is concerned) in a considered manner, one can find oneself inadvertently rendered intestate.
For example, if a testator divorces (or ends a civil partnership) his will takes effect as if his former spouse or civil partner had died before him, subject to express contrary intention. Similarly, marriage revokes a will unless it was drafted expressly in contemplation of the said nuptials. Of course, as a solicitor, Matthew should have known this, but perhaps he took too great a heed of the adage 'A solicitor who acts for himself has a fool for a client.'
Other topics for discussion in future tutorials might be the content of Nanny West’s employment contract (did she breach a condition that both charges should be treated equally?), the grounds for divorce in other jurisdictions or the extent to which the estate could qualify for agricultural, business or even heritage property for inheritance taxes. Who ever thought Downton was an education?
