Joint Tenancy vs Tenants in Common Ireland

Why Property Ownership Structure Matters After Death

When someone dies in Ireland, how their property is held determines whether it goes through probate or transfers automatically. This isn't an academic distinction — it affects how long the surviving owner waits to access the property, whether the deceased's Will has any say in who inherits their share, and how much Capital Acquisitions Tax the beneficiary pays.

The two main forms of co-ownership in Ireland are joint tenancy and tenancy in common. They look identical on the surface — two or more people own a property together — but they behave very differently when one owner dies.

Joint Tenancy: The Right of Survivorship

Under a joint tenancy, all owners hold the entire property together. No individual owner has a distinct, separable share. When one joint tenant dies, their interest passes automatically to the surviving joint tenant(s) by the right of survivorship (jus accrescendi). This happens by operation of law — it doesn't go through probate, and it cannot be overridden by the deceased's Will.

This makes joint tenancy extremely efficient for couples who want the survivor to inherit the property with minimal administrative delay. There's no need to wait for a Grant of Probate for the survivorship transfer, but the survivor may still need to update the title with Tailte Éireann. The property must still be disclosed on Form SA.2 for Capital Acquisitions Tax purposes.

The limitation is that the deceased owner has no control over what happens to their share. Even if their Will says "I leave my share of the house to my children," the survivorship rule overrides the Will completely. The property passes to the surviving joint tenant regardless.

Tenancy in Common: Separate Shares, Separate Control

Under a tenancy in common, each owner holds a defined, divisible share of the property — typically 50/50, but any split is possible (60/40, 75/25, etc.). Each owner's share is theirs to deal with independently. They can leave it to whoever they choose in their Will, sell it during their lifetime, or mortgage it separately.

When a tenant in common dies, their share does not pass automatically to the surviving co-owner. Instead, it forms part of the deceased's estate and is distributed according to their Will (or under intestacy rules if there is no Will). The surviving co-owner retains only their own share. The deceased's share goes through probate and is transferred to the beneficiary named in the Will — which could be the co-owner, but could equally be a child, sibling, or anyone else.

This makes tenancy in common the better structure when co-owners want to maintain control over what happens to their share after death. It's particularly relevant for blended families, unmarried partners, co-owners who are not romantic partners (siblings, parent-child, friends), and anyone who wants their share of the property to ultimately pass to someone other than the co-owner.

Tax Implications: When Survivorship Creates a Problem

For married couples and civil partners, joint tenancy is straightforward from a tax perspective. Inheritances between spouses and civil partners are completely exempt from Capital Acquisitions Tax, so the surviving spouse inherits the deceased's share tax-free regardless of the property's value.

For cohabiting partners, the picture is drastically different. Revenue classifies cohabitants under Group C, with a lifetime tax-free threshold of just €20,000. If a cohabiting partner inherits a half-share of a property worth €500,000 through joint tenancy survivorship, the taxable amount is:

• Value of inherited share: €250,000
• Group C threshold: €20,000
• Taxable excess: €230,000
• CAT at 33%: €75,900

The Dwelling House Exemption may apply — removing the property from the CAT calculation entirely — but only if the inheriting partner lived in the property as their principal residence for the three years before the death, owns no other residential property, and continues to live there for six years afterwards. These conditions are strict, and failure to meet any one of them triggers the full tax liability.

How to Sever a Joint Tenancy

If you currently hold property as joint tenants and want to change to tenants in common — for example, because you're in a blended family and want your share to pass to your children rather than your co-owner — you can sever the joint tenancy.

Severance converts the joint tenancy into a tenancy in common, giving each former joint tenant a distinct and equal share. In Ireland, severance can be done by:

1. Written notice — one joint tenant serves a written notice of severance on the other(s). This is the simplest method and does not require the other party's consent.
2. Mutual agreement — both parties agree to convert the ownership structure, usually with a solicitor drafting a deed of severance.
3. Course of dealing — treating the property as though held in common (e.g., one owner attempting to sell or mortgage "their share") may be treated as an implicit severance, though this is less reliable.

The severance should be recorded with Tailte Eireann (the Land Registry / Registry of Deeds) to ensure the updated ownership structure is reflected on the title. Registration has been compulsory for all property transfers in Ireland since June 2011.

Severance does not affect ownership during the lifetime of both parties — both continue to own and occupy the property as before. The difference only manifests when one owner dies.

Which Structure Should You Choose?

Joint tenancy works best for:

• Married couples or civil partners who want the survivor to inherit automatically
• Couples with no children, or with shared children only, who want simplicity
• Situations where both owners agree the survivor should have the entire property

Tenancy in common works best for:

• Cohabiting couples who want to control who inherits their share (and who may face CAT liabilities under joint tenancy)
• Blended families where one owner wants their share to pass to children from a previous relationship
• Siblings or non-romantic co-owners who each want their share treated independently
• Anyone who wants their share of the property to be governed by their Will

If you're unsure which structure applies to your current property, check the title deed — it will specify whether you hold as joint tenants or tenants in common. A solicitor can confirm the position and, if needed, prepare a deed of severance.

The Bigger Picture

Property ownership is one piece of a broader end-of-life plan. How the property is held interacts with the Will (a tenancy in common share is governed by the Will; a joint tenancy share is not), with CAT planning (the Dwelling House Exemption, Section 72 insurance, and group thresholds all depend on ownership structure), and with the EPA (an attorney's power over property decisions depends on what the EPA instrument covers).
