Not all estates are equal when it comes to probate costs. A straightforward estate with a valid will, one property, and cooperative beneficiaries needs far less professional work. An estate with business assets, foreign investments, or a disputed will costs significantly more. Understanding where your estate falls on this spectrum helps you budget realistically and decide what level of professional help you need. For a full breakdown of all probate expenses, see our guide to probate costs and fees in Ireland.
What makes an estate “simple” or “complex”
There is no legal definition of a simple or complex estate in Ireland. These are practical categories that solicitors and the Probate Office use to describe the level of work involved. The distinction affects how much professional time is needed, how many specialists are involved, and how long the process takes.
How complexity affects each cost category
The table below compares the typical costs for a simple estate against a complex estate across every major category. All solicitor fees are shown exclusive of VAT at 23%.
Solicitor fees
€2,000–€5,000 + VAT
€5,000–€15,000+ + VAT
Probate Office filing fee
€100–€350
€350–€650+
Property valuations
€250–€500 (one property)
€500–€2,000+ (multiple properties or specialist valuations)
Tax advisor fees
Usually not needed
€500–€3,000+ (CAT, cross-border, or business assets)
Statutory advertisements
May not be needed
€200–€500 (newspaper notices to protect against unknown creditors)
Miscellaneous (postage, copies, outlays)
€100–€300
€300–€1,000+
Typical total (before any CAT)
€3,000–€6,000
€8,000–€20,000+
Ranges are indicative. Actual costs depend on the specific circumstances of each estate.
| Cost Category | Simple Estate | Complex Estate |
|---|---|---|
| Solicitor fees | €2,000–€5,000 + VAT | €5,000–€15,000+ + VAT |
| Probate Office filing fee | €100–€350 | €350–€650+ |
| Property valuations | €250–€500 (one property) | €500–€2,000+ (multiple properties or specialist valuations) |
| Tax advisor fees | Usually not needed | €500–€3,000+ (CAT, cross-border, or business assets) |
| Statutory advertisements | May not be needed | €200–€500 (newspaper notices to protect against unknown creditors) |
| Miscellaneous (postage, copies, outlays) | €100–€300 | €300–€1,000+ |
| Typical total (before any CAT) | €3,000–€6,000 | €8,000–€20,000+ |
The single biggest cost difference is solicitor fees. A solicitor handling a simple estate may offer a fixed fee of €2,000 to €5,000 plus VAT because the scope of work is predictable. For a complex estate, solicitors typically charge either a higher fixed fee or an hourly rate (€150 to €350 per hour plus VAT), because the time required is harder to estimate. For more on how solicitors charge, see our guide to solicitors' fees for probate in Ireland.
Factors that increase estate complexity
The table below breaks down each factor that determines whether an estate is simple or complex. If your estate has even one factor in the “complex” column, you should budget for higher costs and a longer timeline.
Will
Valid, clear, uncontested
No will (intestacy), ambiguous, or contested
Property
One property or none
Multiple properties, commercial property, or land
Financial assets
One or two bank accounts, modest savings
Multiple accounts, investments, shares, pensions from different providers
Business interests
None
Sole trader, partnership, company shares, farm
Foreign assets
None
Property, bank accounts, or investments outside Ireland
Beneficiaries
Few, cooperative, clearly identified in the will
Many beneficiaries, disputes, or minors involved
Tax position
Below CAT thresholds or straightforward Group A
CAT liability, cross-border tax obligations, or agricultural/business relief claims
Debts and liabilities
Few or none
Significant debts, secured loans, or unknown creditors
If your estate has any “complex” factors, professional help is strongly recommended.
| Factor | Simple | Complex |
|---|---|---|
| Will | Valid, clear, uncontested | No will (intestacy), ambiguous, or contested |
| Property | One property or none | Multiple properties, commercial property, or land |
| Financial assets | One or two bank accounts, modest savings | Multiple accounts, investments, shares, pensions from different providers |
| Business interests | None | Sole trader, partnership, company shares, farm |
| Foreign assets | None | Property, bank accounts, or investments outside Ireland |
| Beneficiaries | Few, cooperative, clearly identified in the will | Many beneficiaries, disputes, or minors involved |
| Tax position | Below CAT thresholds or straightforward Group A | CAT liability, cross-border tax obligations, or agricultural/business relief claims |
| Debts and liabilities | Few or none | Significant debts, secured loans, or unknown creditors |
Multiple properties
Each property requires a formal valuation for Revenue, which typically costs €250 to €500 per property. If properties need to be transferred or sold, conveyancing fees apply separately — typically €1,500 to €3,000 per property plus VAT. Commercial property or agricultural land may require specialist valuations that cost more.
Business assets
Estates that include a sole trader business, a partnership interest, or shares in a private company require specialist valuation and often need a tax advisor alongside the solicitor. Business Relief may reduce the CAT liability on qualifying business assets, but claiming it requires professional guidance. Farm assets may qualify for Agricultural Relief, which has its own eligibility conditions.
Foreign assets
Assets held outside Ireland can significantly increase both cost and timeline. You may need to obtain a separate grant in another jurisdiction, deal with foreign tax obligations, and navigate double taxation treaties. A tax advisor with cross-border expertise is essential. For estates with international elements, see our guide to cross-border inheritance in Ireland.
Disputes and contested wills
A disputed will or disagreements among beneficiaries can transform a moderate estate into an expensive one. Legal costs rise when matters go to mediation or court. The executor also has a duty to administer the estate correctly during a dispute, which is why professional guidance matters here. Even the possibility of a dispute increases costs, because the solicitor must take extra care to protect the executor's position.
Intestacy (no will)
When there is no will, the estate is distributed according to the Succession Act 1965. An administrator must apply for Letters of Administration (the court document that lets you manage the estate when there is no will) instead of a Grant of Probate. This involves additional steps and requires an administration bond — a financial guarantee set at double the gross estate value. The Probate Officer does not normally require guarantors for the bond unless there are specific concerns. The process typically costs more and takes longer than an estate of similar size where there is a will.
How complexity affects the timeline
A longer timeline means higher costs — more solicitor time, ongoing property maintenance, and extended uncertainty for beneficiaries. The table below shows typical timelines for each stage of probate, compared by estate type.
Gathering documents and valuations
2–4 weeks
4–12 weeks
Revenue filing (SA.2)
1–2 weeks
2–8 weeks
Probate Office processing
8–16 weeks
8–16 weeks (same queue, but queries add delay)
Post-grant administration
4–8 weeks
3–12 months
Total typical timeline
4–6 months
12–24 months
Timelines are estimates. Probate Office processing times vary and are subject to backlogs.
| Stage | Simple Estate | Complex Estate |
|---|---|---|
| Gathering documents and valuations | 2–4 weeks | 4–12 weeks |
| Revenue filing (SA.2) | 1–2 weeks | 2–8 weeks |
| Probate Office processing | 8–16 weeks | 8–16 weeks (same queue, but queries add delay) |
| Post-grant administration | 4–8 weeks | 3–12 months |
| Total typical timeline | 4–6 months | 12–24 months |
The Probate Office processes simple and complex applications in the same queue, so the processing time itself is similar. However, complex estates take longer at every other stage — gathering documents, obtaining valuations, filing with Revenue, and distributing assets after the Grant is issued. For more detail on what affects the timeline, see our guide to how long probate takes in Ireland.
Tax implications: simple vs complex
Capital Acquisitions Tax (CAT) is a tax on inheritances in Ireland, charged at 33% on the amount above the relevant tax-free threshold. The current thresholds are: Group A €400,000 (parent to child), Group B €40,000 (sibling, niece, nephew, or grandchild), and Group C €20,000 (all other relationships). These thresholds are cumulative — they include all gifts and inheritances you have received in the same group since 5 December 1991.
For a simple estate, the inheritance often falls within Group A thresholds and no CAT is payable. A tax advisor may not be needed at all. For a complex estate, CAT planning becomes critical — especially when multiple beneficiaries in Group B or C are involved, when business or agricultural relief is being claimed, or when there are cross-border tax obligations.
How to estimate which category your estate falls into
Most estates in Ireland are relatively straightforward. If you can answer “yes” to all of the following, your estate is likely simple:
If even one answer is “no”, the estate has some complexity. The more factors in the “complex” column, the more professional help you will need — and the higher the cost.
When professional help is essential versus optional
For a genuinely simple estate, a personal application to the Probate Office is manageable. The Probate Office guides personal applicants through the process, and the total cost is typically €600 to €2,000 (filing fees plus minor outlays, for estates under €500,000). Personal applicant filing fees are approximately double the solicitor rate — for example, €700 for an estate valued up to €500,000. This option suits executors who are comfortable with paperwork and have time to manage the process.
Professional help becomes essential when the estate involves any of the complexity factors described above. In particular:
- A solicitor is strongly recommended for estates with multiple properties, business assets, disputes, or intestacy.
- A tax advisor is recommended when there is a potential CAT liability, cross-border assets, or claims for Agricultural or Business Relief.
- A property valueris needed whenever the estate includes real property — Revenue requires a formal valuation.
For complex estates, these professionals ideally work together from the start. Coordinated service avoids duplication, catches issues early, and typically results in a shorter timeline. For more on deciding whether to engage a solicitor, see our guide to DIY probate versus professional help.
