Delay in Estate's distribution to beneficiaries

Is there any reason that would delay an Estate's distribution to beneficiaries as other than being notified I am a one of the beneficiaries
by solicitors in Ireland acting for the Administrator some 20 months ago, I have no other details.

Strangely, I asked my sister living in the UK (I live in Australia) as was curious re the Estate but she said she knew nothing and had not
heard from the solicitors. Very weird as she would be one of four beneficiaries. The other two beneficiaries are unwilling to speak with
me and one is the Estate's Administrator. Sadly, it is a complicated long standing situation and is not likely to change unfortunately.

By reading here and recently searching I have found the Letters of Administration were granted September, 2020 and my deceased
Uncle's house was sold for Euro130,00 in December, 2020? I was told by the solicitors I would not need a PPS Number and posted
here in May, 2020 when I was told this meant my distribution would be under Euro26,000 - 80% of 32,500.

Any suggestions on the above would be appreciated as I have not lived in Ireland for over 32 years so have no idea what the outcome
should be but would be grateful for the inheritance if I should ever receive it.

You mention that you were notified by solicitors acting for the administrator that you were a beneficiary.
Have you talked to them as I would expect that they would be making the payments. Could there other assets that they may be waiting to be sold off before making the distributions?

Thank you for your reply, I assume is it more the norm for the Estate solicitors to pay the distributions?
However, the solicitor's letter stated the Administrator would be paying distributions on the Grant of Administration.
There may well be other assets to be disposed of as you suggest. My close relatives in Ireland have all passed away
in recent years so I only have information I have found myself.

Last year I asked the solicitors for the information I am entitled to receive (their wording) and they replied they are not
permitted to discuss this matter other than with their client, they would contact me in due course when in a position
to finalise this administration.

Would it be normal practice for the Estate solicitors to advise beneficiaries of the Grant of Administration last
September and, as they are not paying the distributions, what may be required before their role is finalised?
Or, I guess, they are following their client's instructions to not inform me?
